COUPLING.

SPECIFICATION forming part of Letters Patent No. 654,735, dated July 31,1900.

Application led March 30, 1900. Serial No. 101740. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, LINwooD F. JORDAN, a citizen of the United States,residing at Portland, in the county ot' Cumberland and State of Maine,have invented certain new and useful Improvements in Couplings; and I dohereby declare the followingto be a full,clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in couplings, and especiallyrelates to means for coupling flexible pipes either of lead, rubber, orwoven material. It is designed tobe' used so that the ends of the-pipesmay be readily and easily joined and to obviate the need of solder, redlead, dac., or, as in the case of lead pipes, ot wiping the joints, andit still further obviates the need of wash ers or gaskets, whichare soessential in the ordinary formsof coup'-A lings now used. L L To thisend it consists of a body provided with a beveled or flaring seatagainst which the ends of the pipe may rest when in position. It furtherconsists of means for expanding the ends of the pipes to be coupled andin means for drawing the pipes together and holding them upon -thebeveled seat so that a perfectly7 water-tight connection can be madewithout the intervention of gaskets, washers, or other additional means.

In joining the ends of pipes it has been found very difficult to makeatight joint without the use of some cernenting material, as red lead,solder, or, as in the case of lead pipes, wiping the joints. This causesadditional labor and expense, and, besides, when it is desired to breakthe joints the process very often results in the destruction of thepipe. In my invention this diftlculty is done away with, for by forcing,as I do, the end of a pipe which has been previously iiared over aflaring seat and causing a portion ot the Haring seat to extend withinthe tiaring end of the pipe and holding the same close thereon a tight-joint is made without the use of any further materials, for it presentsa larger and longer bearingthan is usually the case in coupling pipesend on, and at the same time by turning back a portion of the projectingend of the pipe makes a tight and' at the same time a firm joint.

In the drawings herewith accompanying and forming a part of thisapplication, Figure l is a central vertical section of my improvedcoupling, showing a form used for coupling two lengths ot pipe. Fig. 2is a central vertical section showing ineans of coupling pipe to somesource of supply, as to the watertank of a locomotive. Fig. 3 is acentral vertical section showing a slightly-different form of a doublecoupling. Fig. 4 is a central vertical section of the combination asshown in Figs. 2 and 3. 4

Same letters of reference refer to like parts in all .the figures.

In said drawings, A represents portions of la pipe to be coupled; B, ahollow conical eX- pander adapted to be driven within the ends of thepipe to cause the same to be expanded I and which is so driven withinthe ends of the pipe that the ends thereof extend beyond the saidexpansion-ring.

O represents rings adapted to be driven over the pipe to be coupled andprovided with a sli ghtly-taperin g internal bore to correspond `withthe taper on the pipe caused by driving the conical expanding-ring Binto the pipe. These rings may be screw-threaded on their exterior, asshown at B' in Fig. 3, or may be provided with an annular flange D, asshown in Figs. l and 2. The body E, to which the pipe may be coupled,consists of a hollow tubular portion screw-threaded on its exterior, asseen at E', and provided with a beveled or flaring shoulder F to receivethe ends of the pipe A.

G, Figs. l and 2, is a ring screw-threaded on its interior, adapted tobe screwed over said coupling in order to draw the ends of the pipe downover the beveled edges of the body.

The edge H of the bevel on the face of thecoupling is adapted to abutagainst the hollow expanding-rings B, which. are-,inserted within thepipe. From this it will be readily seen that as the ring G is screwed.up upon the coupling the edge of the daring face will bear against theconical'rings and drive the same within the pipe, causing the same to beslightly expanded, as the-smallest diameter of said flaring seatcoincides with the diameter of the expanding-rings. The end of the pipeis prevented from excessive expansion by the rings C, which also tend to'force the IOO ring vGv screw-threaded on its interior andrv 'end 'ofvthe pipe down upon the Haring seat, l a tight joint with the Haringwall of the seat.

thereby filling inthe seat and making a tight jointbetw'een the interiorWall of the pipe and daring seat. It will be seen that the ring G,. asalso the ring C, may be either providedl with a iiange G', so that the4pipe inay be drawn tightly downv over thecollar,

or the rings may be provided with screwthreads, which accomplish thesame result.' In either form the rin gsare interiorly flaring,

so as to conform to the Iiare on the end of theVV pipe to becoupled,caused by driving the ex-Y pansion-ring on the end of the pipe. Thisiiaring interior also serves the additional purpose of drawing the pipeup onto the fiar-- ing seat.

Fi^g. 4f showsA a slight. m'odiication of my coupler combining in onecoupling bothA the anged ringand the screw-threaded ring. In this itwillbe seen that the pipes to be joined are provided with the conical-shapedexpanding-rings B,.the -main body E having beveled faces F on each side,the edges H of which areadapted to abut against the conicalexpanding-rings and force the samewithin the:

pipe, causing at the same time a portion of the pipe end to protrude andfit tightly over-thev flaring seat. It .also shows the drawing-rings,

one, C, having both an interior taper .I andi exterior taper K and anannular iiange` D, a

also provided with a iiange D', adapted te bear against the iiange onthe drawing-ring and force the end of the pipe upon the beveled seat ofthe main body. The main body E is also screw-threaded both exteriorlyand interiorly, so as to allow the ring G yto be screwed up on itandalso to allow thelring C, which is screw-threadedv on its exterior, asshown atM, to be screwed therein.

I do not wish to limit myself to the `exact formsof construction shown,for some ofthe mechanical details may be altered or changed withoutdepartingvfrom the spirit of my invention;

" Having thus described my invention and its use, I claim- In acoupling, a ppe,.an inde-pendent conical expanding-ring inserted in.theend of said pipe, a main body provided'with-a flaring seat and meansfor forcing the flaring endof the pipedown upon said Haring seat,whereby a close join-t is formed between saidseat and the interior ofsaid pipe.

2. In a coupling, a iiexible pipe, an indewithi'nthe end thereof,'ab.ody provided with v a arinig seat to receive the end of thel pipe,

3. In a coupling, a flexible pipe, an independent conical expanding-ringwithin said pipe, the end of the pipe extending beyond said ring, a bodyprovided with a daring seat toreceive the protruding end of the pipe,interiorlyiiiaring ring surrounding the outside of the pipe and providedwith an annular ange, a threaded ring provided with an an-V nulariian'ge adapted to be screwed irito the said bodyand force the end ofthe pipe down gover said daring seat, whereby a tight joint is formed.

4. In a coupling, a'lexible pipe, an independent conical expanding-ringwithin said pipe, the end of said pipe projecting beyond saidring,atubular central body provided with a tapering seat surrounding theopening, the smallest diameter of said tapering` seat ycorrespondingwi-th the-diameter of said expanding-ring and means-for forcing saidpipe down uponl said seat, the cone of theseat entering the fiari-ngendof the pipeand driving said independent `expandingwing within thepipe.
